[CAUT] Which S&S replacement action parts?

[Barbara Richmond]

Hi David,

I'm glad you brought this up.  I was going to ask folks about their 
technique, but I'm sort of shy.  ;-)  I do the same, though I was slightly 
unnerved by a colleague when he looked at me like I was from Mars when I did 
it.  I will have the chance in about a week and a half to check out one of 
the pianos I repinned recently.  It will be interesting to test out a few of 
those centers.

Different flange cloths require different "recipes for repinning"--as I call 
them.   The most difficult for me is pinning the jack.  I guess it's because 
it is pinned sort of loose and it takes quite a sensitive touch to get 
consistent results.
